Locking and unlocking
If you prefer to use your own backup tools or just make a file copy, nbackup’s lock-unlock mode comes into view.“Locking” means here that the main database file is frozen temporarily, not that no changes can be made to the database.Just like in backup mode, mutations are directed to a temporary delta file;upon unlocking, the delta file is merged with the main file.
As a reminder: nbackup.exe
is located in the bin
subdirectory of your Firebird folder.Typical locations are e.g. C:\Program Files\Firebird\Firebird_3_0
or C:\Program Files\Firebird\Firebird_2_0\bin
(Windows) or /opt/firebird/bin
(Linux).There’s no GUI;you launch it from the command prompt or call it from within a batch file or application.
